Many disappointed Watchmen fans were turned away from a full crowd as the Watchmen panel further explored the alternative world of the 1980's at the 2008 Comic Con in San Diego. Last year the crew unveiled a poster for the movie. This year they showed more detailed clips and talked about the mature aspect of the movie.
One notable point is that Zack Snyder claims the Watchmen is hovering around the 3 hour mark right now. He mentions that the Warner Bros. Studio wants that trimmed down to 2.5 hours by release date which already has die-hard fans mentioning a director's cut.
Snyder's doing a fantastic job of P.R. with the movie by keeping interest for the fans who are aiming for the moon. Many consider the original graphic novel of the Watchmen by Alan Moore and Dave Gibbons to be the Citizen Kane of their world. A movie version has been in the works for years and many will not tolerate anything less than the best movie possible.
